Television front frame four-window hole deburring shaping die

Abstract

The invention discloses a television front frame four-window hole deburring shaping die. The television front frame four-window hole deburring shaping die comprises an upper die body and a lower die body. The upper die body comprises an upper cover plate, an upper block, an upper die base, an upper base plate and a stripper plate which are sequentially connected from top to bottom. The lower die body comprises a lower supporting plate, a lower block, a lower die base and a lower die plate which are sequentially connected from bottom to top. A set of inserting cutters is symmetrically installed on the upper die base and comprises the first inserting cutter and the second inserting cutter. A set of shaping blocks is movably arranged in the positions, corresponding to the first inserting cutter and the second inserting cutter, of the lower die plate and comprises the first shaping block and the second shaping block. The first shaping block and the second shaping block are controlled through a first spring and a second spring which are installed on the two sides of the lower die base correspondingly. The stripper plate is further provided with an insert. According to the television front frame four-window hole deburring shaping die, the structure is simple, the working continuity is good, and the apparent shape of a workpiece and the deburring size precision of the workpiece can be ensured; the deburring shaping quality is high, and the working period is greatly shortened; and the working efficiency is high, and the industrial cost is low, so that the economic benefits are improved conveniently.

Description

technical field [0001] The invention relates to the technical field of burring shaping molds, in particular to a burring shaping mold with four windows on the front frame of a TV. Background technique [0002] At present, there are two main types of burr treatment for the four window holes of the front frame of the TV: one is only for the burr treatment of the holes, which is prone to the phenomenon that the front frame is larger in the middle and smaller at the two ends after the burr is pressed, which seriously affects the aesthetics of the front frame; One is to use holes for pressing and burring, and at the same time, the side push shaping structure is adopted around the frame. The side push shaping structure is a lateral forming block device with elastic reset for the lower mold, and a knife insertion device for the upper mold to complete side shaping. The purpose is to reshape the front frame, which is large in the middle and small in the two ends. However, the struct...

[0002] At present, there are two main types of burr treatment for the four window holes of the front frame of the TV: one is only for the burr treatment of the holes, which is prone to the phenomenon that the front frame is larger in the middle and smaller at the two ends after the burr is pressed, which seriously affects the aesthetics of the front frame; One is to use holes for pressing and burring, and at the same time, the side push shaping structure is adopted around the frame. The side push shaping structure is a lateral forming block device with elastic reset for the lower mold, and a knife insertion device for the upper mold to complete side shaping. The purpose is to reshape the front frame that is big in the middle and small in the two ends

However, the structure of the traditional burr shaping mold is complex, the mold assembly and processing are cumbersome, and the block generally adopts a segmented structure, which requires pre-assembled blocks, which requires a large workload, low work efficiency, high industrialization costs, and poor economic benefits.
